Ohio Gov. John Kasich spoke with CNN's Ryan Nobles in an interview for the "RunningMate" podcast

Kasich said Trump has yet to say or do anything that would disqualify him as the nominee

(CNN)Mitt Romney is considering ways to block Donald Trump from winning his party's nomination and the Republican establishment is mounting a last-ditch effort to derail the billionaire real estate mogul.

Marco Rubio endorsed the #NeverTrump movement on Twitter, but then begrudgingly said he would support the eventual Republican nominee during Thursday night's debate.

But Ohio Gov. John Kasich is more clear when it comes to Trump. He is refusing to rule out supporting the frontrunner, saying he just can't get on board with the #NeverTrump coalition.

"I want to see how this all plays out. I mean I think when you are battling in the arena, with all the people that were once there. There was 16 of them and we are now down, I am the last governor and there is five of us in the race," Kasich told CNN's Ryan Nobles in an interview for the "RunningMate" podcast. "When you are in the arena you develop some degree of respect for people who have been in the arena, and so we will see how it goes."

The Ohio governor said that Trump has yet to say or do anything that would disqualify him as the nominee.

"I mean it is always possible that somebody could do something that is so egregious that I would not want to be behind them, but let's see," Kasich said adding, "And I am not counting myself out on that."

Kasich talked with "RunningMate" shortly before Super Tuesday, but after Trump repeatedly declined to disavow an endorsement from former Ku Klux Klan leader David Duke in a "State of the Union" interview with CNN's Jake Tapper. Trump later said he disavowed Duke's endorsement.

When asked specifically if Trump had said or done anything that would disqualify him from earning the governor's support he replied, "I've said what I am going to say about that."

Kasich has argued emphatically that his ability to win his home state of Ohio makes him the best candidate for Republicans looking to win the White House. But Kasich has been trailing Trump in most polling ahead of Ohio's Republican primary May 15.

Unlike his fellow opponents Rubio and Sen. Ted Cruz, Kasich has avoided engaging with Trump on the campaign trial. He told Nobles that insulting the billionaire is not the way to beat him.

"The idea that all you do is spend your time trashing somebody else, that is not the way I do politics," Kasich said. "And I have run in more races than all the people on the stage now put together."

Kasich also reiterated his belief that he believes he will win the GOP primary in Ohio and that it will effectively reset the race.

"Those people who express these concerns don't have a lot of knowledge of how it all works," he said. "And we believe If we are able to win Ohio which I believe we will be able to do it will be a whole new day."

Kasich gave Trump a scare in Vermont Tuesday, falling just 1,400 votes shy of the Republican front-runner there. Kasich has also focused heavily on Michigan, which votes Tuesday, but has failed to gain much traction there so far in polls.
